The invention discloses an automatic emergency braking function triggering opportunity correction method considering steering constraint, and belongs to the technical field of advanced driving assistance systems and unmanned systems, and the method comprises the steps that a sensor collects motion parameters of a vehicle and a target, calculates longitudinal collision time, calculates steering time of the vehicle, and collects current scene information; and determining a special scene correction factor, calculating a trigger condition, and issuing a braking instruction. According to the method, the accuracy of the AEB triggering condition is improved by calculating the steering time, so that the reasonability of the automatic emergency braking triggering opportunity is ensured, and large-scale mass production application of the automatic emergency braking function is realized; by determining the correction factor of the special scene in the vehicle driving process and fully considering the risk scene in the vehicle driving process, the accuracy of the triggering condition is improved, the possibility that the vehicle has an accident is reduced, and safe driving is ensured.

    本发明公开了一种考虑转向约束的自动紧急制动功能触发时机修正方法,属于高级驾驶辅助系统和无人驾驶系统技术领域,包括传感器采集自车和目标的运动参数,计算纵向碰撞时间,计算自车转向时间,传感器采集当前场景信息,确定特殊场景修正因子,计算触发条件,下发制动指令。本发明通过对转向时间的计算以提高AEB触发条件的准确性,从而确保自动紧急制动触发时机的合理性,实现自动紧急制动功能的规模化量产应用;通过对车辆行驶中特殊场景修正因子的确定,充分考虑车辆行驶过程中的风险场景,从而提高触发条件的准确性,减少车辆发生意外的可能性,确保安全驾驶。
